Acute cysticercosis caused by Cysticercus tenuicollis in lambs

Abstract

Twelve 30‐ to 75‐day‐old mixed breed lambs were examined in an intensive system because of sudden recumbency and death. Clinical examination revealed sudden recumbency, visceral pain, and auscultation of respiratory crackles. Lambs died shortly (between 30 minutes and 3 hours) after the onset of clinical signs. The lambs were necropsied, and after routine parasitology, bacteriology and histopathology procedures, the occurrence of acute cysticercosis caused by Cysticercus tenuicollis was confirmed. The use of the suspect infested feed (newly purchased starter concentrate) was discontinued and other lambs of the flock were treated with praziquantel (15 mg/kg, single dose, orally). After these actions, no new cases were observed. The present study showed the importance of preventive measures against cysticercosis in intensive sheep farming systems which include proper storage of feed, preventing feed and environmental access by potential definitive hosts, and implementing consistent parasite control programs in dogs that are in contact with sheep.

Determining the decreasing trend of maternal immunity against small ruminant morbillivirus in goat kids

“…According to the study of Abdollahi et al. (2020), in the conditions of traditional lamb and goat kid rearing system (semiintensive system) in Iran, about 50% of lambs and goat kids suffer from FPT because lambs and goat kids are with their mothers and there is no monitoring on receiving sufficient colostrum. Therefore, it is better to conduct another similar study in traditional (semi intensive) goat breeding systems.…”

“…In the present study, the number of male and female neonates in both control and case groups was almost equal. It seems that in the semiintensive system of sheep and goat breeding, the occurrence of FPT in male neonates is less (Abdollahi et al., 2020). In this study, colostrum was fed manually to the neonates in intensive system and there was no difference between the FPT rates in them.…”
